Question 156362
{{{graph(300,200,-5,5,-5,5,2x+1)}}}

This is the graph of y = 2x + 1.  Then, you would shade the area to the left of the line since this is the area where y is greater than.  Also, the line should be a dashed line instead of a solid line, which indicates y must be strictly greater than 2x + 1 and cannot equal 2x + 1.
